Clare Ave Extension

Welland

Project scope

In the fall of 2015 Coldstream Concrete supplied a project to Gibbons Contracting Ltd in the City of Welland, Ontario. It consisted of a double run – open bottom box culvert with a span of 7.316m and a rise of 1.524m. The 9.0m wide road joined two subdivisions together in an area with extreme high water tables and poor soils. This all precast job consisted of 24 precast footing units, 24 precast open bottom box units and 8 different sized wing wall units.

The total precast installation time in late fall was 3 days.

Central Elgin County

On October 15, 2015 Coldstream Concrete supplied an open bottom precast culvert that had a 11.5m span and 3.5m rise to the County of Central Elgin. Relatively dry conditions were very helpful during the installation due to the size of the watercourse and excavation. The culvert consisted of 15 units to create a 16m wide roadway. This single structure replaced a design for a dual box culvert. This is turn reduced the total project cost and created better watercourse flow. Coldstream also supplied precast concrete footings.

The total installation time for footing and bridge elements was under 2 day.

Chinnick Drain and Pump Station

Chinnick Drain and Pump Station

Mun. Chatham Kent

In June 2015 Coldstream Concrete supplied 2 large pump stations that were 7.2m x 3.8m x 6.2m deep to the Chinnick Drain and Pump project in the Municipality of Chatham Kent. These chambers house pump intakes and collect water from the Chinnick Drain which is then pumped into Lake St. Clair. The entire one end was open to receive water from the drain. Due to the high water levels buoyancy issues had to be considered. The 3 walled chamber caused structural problems. This was remedied by inserting 25m rebar into preformed vertical tubes that extended through all the riser sections, base and cap. This created horizontal and vertical reinforcing grid and joined all the elements together. Each chamber consisted of 9 units. All 18 united were installed in the winter with water issue over 1.5 days.

Ormston Subdivision, Kitchener

PRECAST CONCRETE INLET TRENCH

On May 23, 2018 Coldstream Concrete Ltd. supplied a seven-piece precast concrete trench complete with approach slabs and maintenance chamber to the Ormston Subdivision in Kitchener, Ontario. The trench and all of its components were constructed using epoxy reinforcement and came equipped with concrete corbels on either side to support the precast approach slabs. Each trench piece has 6 separate galvanized steel angles cast into the concrete corners for protection and roadway grating.

The trench was installed and backfilled in less than two days.

Fleming Road, Plympton-Wyoming

PRECAST CONCRETE CULVERT

On July 11th Coldstream Concrete Ltd. supplied a 12-piece “all skewed box culvert” for the town of Plympton-Wyoming. Each piece of he 3.6m span by 2.1m rise box culvert was constructed on a 30-degree skew. This was done in order to avoid large/heavy end units which are typical for precast skewed end culverts. Due to the fact that all pieces where designed to the same physical dimension (without large heavy end units) all 12 pieces were installed quickly and safely by 2pm the day they were delivered.

Grey Rd 10, Grey County

The culvert spans 5.5m and sits 2.5m tall. In typical precast fashion it was installed in less than one day, resulting in shorter road closure times for the public.

The second phase is set to be installed in mid August which includes a second precast culvert with similar properties of 10 + 590.

Rock Glen Road

On September 14, 2018, Coldstream Concrete Ltd. supplied a large box culvert (6m span x 2.4m rise) to the Municipality of Lambton Shores. The culvert consisted of 8 standard box units weighing 83,400 lbs each, and 1 end unit with a skew of 35o weighing 87,600 lbs. The skewed end unit was surrounded on both sides by the London Boulder Block retaining wall system (also produced by Coldstream Concrete). This system always provides an easy and decorative finish to any culvert. All 9 pieces were installed in half a day, and back-filled later the same day. The waterway was back up and running by the start of the following day.

Edgevalley Subdivision

During the 2018 summer months, Coldstream Concrete Ltd. supplied custom heavy precast and underground site servicing products to the northeast corner of London, Ontario. Phase one of this 25.4-hectare site backs onto the Thames river and will be home to over 130 detached residential lots. The SWM facility outlets into the Thames River and features a 31.5m precast concrete box culvert with a 90-degree bend, a precast three-sided, open-bottom culvert with footings, three precast headwalls and a custom precast outlet chamber. This chamber spans 5.3m x 4.8m x 3.0m deep and transfers water flow from a 2400mm diameter precast pipe + 1095mm x 1730mm elliptical pipe into a 3.0m x 2.4m box culvert outlet. When driving down Highbury Avenue North take a look at the development.

Project scope

On December 6, 2018 Coldstream Concrete Ltd. supplied an 11-piece “ALL SKEW” precast concrete box culvert to Southshore Contracting of Essex County Inc. in Chatham Kent, Ontario. The culvert spans 2.74m, sits 2.13m tall and is 20m long. Each piece was built in our custom formwork with a 30-degree skew. Installation took one full day as mother nature was not cooperating.
